Abstract (en)
A method for updating a network topology in a multi-protocol label switching system includes that network management system obtains network topology data from a node, then judges whether the current network topology is changed, and when changed, update the local network topology data with the network topology data. A corresponding system is also provided, including an obtaining unit to obtain network topology data from a node, a judgment unit to judge whether the current network topology is changed according to the network topology data and to trigger the update unit when it is changed, and a update unit to update the network topology data in the network management system with the network topology data. In the disclosure, the reality of the Multi-Protocol Label Switching Transport Profile (MPLS-TP) network topology is greatly improved, and it is more convenient and accurate when the network management system is utilized to perform network management.
